When the technique is used for wall glazing, the entire surface is covered, often showing traces of texture (French brush, parchment, striae, rag rolling). Either oil-based or water-based materials are used for glazing walls, depending upon the desired effect. Kerosene or linseed oil may be used to extend the "open" or working time of oil-based ...

In the 19th century two glazing techniques revived by Minton were: 1. Tin-glazed pottery in the style of Renaissance Italian maiolica and, 2. The pottery of coloured glazes decoration over unglazed earthenware molded in low relief. At the Great Exhibition of 1851 and at the International Exhibition of 1862 [6] both were exhibited.
Early ceramics were porous, absorbing water easily. It became useful for more items with the discovery of glazing techniques, which involved coating pottery with silicon, bone ash, or other materials that could melt and reform into a glassy surface, making a vessel less pervious to water.
Underglaze is a method of decorating pottery in which painted decoration is applied to the surface before it is covered with a transparent ceramic glaze and fired in a kiln. Because the glaze subsequently covers it, such decoration is completely durable, and it also allows the production of pottery with a surface that has a uniform sheen.
